CBS news reports on an international groups analysis of methods to reduce global temperatures through solar radiation management. The solutions are not meant to replace efforts to reduce greenhouse gases but are to be thought of as stop gap measures. It would theoretically be possible to bring global temperatures to preindustrial levels of 250 years ago. There are questions about who would set the global thermostat and what are the unintended consequences of global temperature reduction. A report from the Bipartisan Policy Center in the US is also looking at geoengineering solutions.
